Day 1:Observations • The environment that the fish is in is in good condition, • the water is clean which provides a good habitat for the fish. We have put as much water as we can so the fish has a lot of space to swim, but not so much that there is no exchange between the plant and the water. • It has oxygen to breath. • The plants are healthy; the terrestrial plant is on top of the moist soil, it is a large healthy plant that does not yet show signs of withering. We had to trim the beautiful

WHAT IS SCIENCE? Why does the apple fall down and does not go up instead? How does a pulley help in drawing water from the well? Why does the clock move in a clockwise direction at specific intervals and not in the anticlockwise direction? What causes the dispersion of white light? What causes the cell division? How does a cocoon metamorphise into a beautiful butterfly? What causes the day and the night? All of these involve some scientific principles or laws, whether the law of gravity, the rotation

Deforestation Environmental Science SCI-204 iLab 1 People relay on products from rainforest everyday and never realize it. Today, people around the world use woods that come from rainforest for products like desk, flooring, instruments, and many other products made from exotic woods. “Tropical forests yield some of the most beautiful and valuable woods in the world, such as teak, mahogany, rosewood, balsa, sandalwood and countless lesser-known species.” (Rainforest Alliance, 2014) Many medications

The Study of Interactions between mussels and their Environment, as well as, between different species of intertidal organisms within a particular Intertidal Community By Arlene Reynolds California State Polytechnic University, Pomona, CA . Abstract. (The relationship between mussels and intertidal organisms within a particular community in the intertidal zone is a great example of the competitive exclusion principle. The alternative hypothesis for this study would be that there is a direct relationship

Crystallization is the (natural or artificial) process of formation of solid crystals precipitating from a solution, melt or more rarely depositeddirectly from a gas. Crystallization is also a chemical solid–liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs. In chemical engineering crystallization occurs in a crystallizer. Crystallization is therefore an aspect ofprecipitation, obtained through a variation of the solubility

Henry failed in securing the French crown for himself as well as the partition of France to himself, Charles and Bourbon, after the Battle of Pavia in 1525. Alongside this, the failures of Henry’s campaign during the war with France including the evaporation of Wolsey and Henry’s passing enthusiasm for another intervention. Source 1, a painting of the Field of the Cloth of Gold, demonstrates a grand celebration made up of extreme wealth, however, it does not comment on the financial side of the spectacle

PHYSICAL CHANGE Physical changes are changes affecting the form of a chemical substance, but not its chemical composition. Physical changes are used to separate mixtures into their component compounds, but cannot usually be used to separate compounds into chemical elements or simpler compounds.[1] Physical changes occur when objects or substances undergo a change that does not change their chemical composition. This contrasts with the concept of chemical change in which the composition of a substance

Chemical Reaction A chemical reaction is a change of a substance into a new substance that has a different chemical identity. A chemical reaction occurs with physical effects, like the emission of heat and light, the release of gas, the change in color, or the presents of precipitate. There are several different types of chemical reactions, such as synthesis reaction, decomposition reaction, single displacement reaction, the double displacement reaction, combustion reaction, and the acid-base reaction
